Ingredients

1/2 cup butter, softened
1/3 cup granulated sugar
3 tbsp powdered sugar
1 egg, room temperature
2 tsp vanilla extract
1 1/2 cups all-purpose flour
1/4 tsp salt
1 tsp baking powder
1/2 cup rainbow sprinkles (for rolling)

Cake-Flavored Buttercream

6 tbsp butter, softened
1/4 tsp cake batter extract
1 cup powdered sugar
3 tbsp heavy cream

Optional Topping

Whipped cream

Step-by-Step Instructions

Preparing the Ingredients

First, preheat your oven to 350°F and line a baking sheet with parchment paper. Then, measure all ingredients carefully to maintain consistency. Let the butter and egg sit at room temperature so they blend smoothly. Meanwhile, prepare your sprinkles in a small bowl for easy rolling later. This step helps streamline the process and keeps your dough from overmixing once everything comes together.

Cooking Instructions

Start by creaming the butter, granulated sugar, and powdered sugar until smooth. Next, add the egg and vanilla extract, mixing until fully combined. Then, incorporate the flour, baking powder, and salt just until the dough forms. After that, scoop six equal portions, roll them into balls, coat them in sprinkles, and flatten slightly. Bake for 11 minutes, then allow the cookies to cool on the pan before transferring to a rack. Meanwhile, whip the buttercream ingredients until fluffy, then frost each cooled cookie and top with whipped cream if desired.

Tips for Perfect Results

Common Mistakes to Avoid

Avoid overmixing the dough, since it can lead to dense cookies instead of soft ones. Also, do not skip chilling after baking, because these cookies taste best when served slightly cold. Another mistake includes flattening the dough too thin, which reduces the signature thick texture. Finally, always measure flour correctly to prevent dryness.

Pro Tips for Better Flavor

For richer flavor, use high-quality vanilla extract and fresh butter. Additionally, a touch of cake batter extract gives that classic milkshake-style taste. If you want bakery-style presentation, pipe the frosting in a swirl rather than spreading it flat. These small adjustments create a more copycat baking experience with better visual appeal and taste.

Serving and Storage

How to Serve

Serve Crumbl Funfetti Milkshake Cookies chilled for the best texture and flavor. The cool buttercream pairs perfectly with the soft cookie base, creating a balanced bite. These cookies work well for birthdays, parties, or casual desserts. You can also pair them with milk or a vanilla milkshake for a complete treat.

How to Store Leftovers

Store leftover cookies in an airtight container in the refrigerator for up to four days. Before serving, let them sit at room temperature for a few minutes to soften slightly. If you plan to store unfrosted cookies, keep them at room temperature and frost just before serving for freshness.

Conclusion

Crumbl Funfetti Milkshake Cookies offer a fun and flavorful baking experience that brings bakery-quality results into your home kitchen.
